BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention is related to an adjuster for an elevated floor,and especially to such an adjuster for an elevated floor that can lowerthe height of an assembled elevated floor, and can adjust the height ofthe elevated floor above the latter; it has a wide range of application,and can reduce waste of space, it is suitable for use in novel and usedspaces of offices.

2. Description of the Prior Art

Following advance of science and technology, people contact more andmore lines for use; particularly in office buildings, various lines(such as networks and cables) are arranged in a mutually crossing andgathering mode. Therefore, at the initial of construction of an officebuilding, pipelines are embedded in advance; however, the initialplanning often is unable to meet the requirement of continuous extensionof pipelines afterwards, and pipelines are differently required indifferent arts.

As to the above stated situation, elevated floors are generallyprovided; and various pipelines are embedded in channels under theelevated floors. A conventional adjuster for an elevated floor “A” isshown in FIG. 6, which comprises a floor plate “B”; the floor plate “B”is provided with a connecting hole “C” to connect a threaded pipe “D”which has therebeneath a nut “E”, and a footing seat “F” provided on theupper end thereof with a thread is thread connected with the threadedpipe “D” and the nut “E”, thereby the footing seat “F” can be used toadjust height of the floor and then can be fixed by using the nut “E”.The above structure can acquire the function of hiding pipelines;however, it still has the following defects:

-   1. The floor itself has a thickness of about 3 cm, plus the footing    seat and the fixing nut beneath the footing seat (about 1.5 cm), an    elevated floor after assembling will have a height of at least 6 to    10 cm, and this is the maximum limitation of such elevated floor in    assembling and production presently; for a new building preserved    with larger heights in space, it will not result a too large problem    in space; but for an old building with lower indoor heights    originally, it will result waste of space in that the indoor heights    will be reduced to make feeling of oppression.-   2. A conventional elevated floor structure has a footing seat screw    connected with the threaded pipe and further has the nut beneath the    threaded pipe for fixing the footing seat, when the floor is    adjusted to a suitable height, by pressing tight of the nut to fix    the footing seat, the footing seat can be avoided from loosening in    use to fail in supporting the floor. However, in fixing the footing    seat with the nut, an adjustment tool shall be extended in from one    side of the floor for adjustment, so that the side of the floor    shall be left with a space for extending of the tool therein, and    for the convenience of adjusting the nut; the thickness of the nut    shall not be too small that may induce inconvenience of adjusting.    According to the above stated causes, the height after assembling of    the conventional elevated floor is unable to reduce, and adjusting    for use of the floor will be quite inconvenient.

In view of the above defects to be solved, an adjuster for an elevatedfloor not only can have the total height of the elevated floor reduced,but also the elevated floor can have its height adjusted from above thelatter; the inventor provides the present invention based on hisprofessional experience of years and continuous studying and developing.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

Referring firstly to FIGS. 1 and 2 showing a preferred embodiment of anadjuster 1 for an elevated floor 2 of the present invention, theadjuster 1 is connected with a connecting hole 21 provided on theelevated floor 2. It comprises mainly: a threaded pipe 3, a footing seat4 and a fixing screw 5.

A bush 22 is provided between the threaded pipe 3 and the connectinghole 21 on the elevated floor 2, and has an inner hexagonal hole 221.The threaded pipe 3 is in the form of an inversed “T” and has an innerthread 31, and has on the bottom end thereof a circular base 32. Theupper portion of the threaded pipe 3 is a hexagonal stub 33 forconnecting with the inner hexagonal hole 221 of the bush 22.

The footing seat 4 has a base 41 for standing on the ground, the footingseat 4 is provided on the external upper end thereof with an externalthread 42 for threading and connecting with the threaded pipe 3, and thefooting seat 4 further has an hexagonal adjustment hole 43 on its upperend.

The fixing screw 5 is mounted above the footing seat 4 and is threadconnected into the threaded pipe 3, the fixing screw 5 has a hexagonalthrough hole 51 extending from top to bottom, the inner tangent circleof the through hole 51 is larger than the outer contact circle of thehexagonal adjustment hole 43 of the footing seat 4.

Referring to FIG. 3 showing use of the present invention, when presentinvention is used to assemble with the elevated floor 2, the footingseat 4 can be rotated to adjust the elevated floor 2 to a suitablelevel, then the fixing screw 5 above the footing seat 4 is rotated tomove downwards, and the footing seat 4 can be pressed tight for fixing.When the ground is uneven, or the elevated floor 2 needs to be slightlyadjusted in height, the fixing screw 5 is loosened, and an adjustmenttool (not shown) can be extended through the through hole 51 of thefixing screw 5 from above the elevated floor 2 to be inlaid in theadjustment hole 43 of the footing seat 4 for the convenience ofadjusting the displacement of the threaded pipe 3 relative to thefooting seat 4, while at the same time, the elevated floor 2 is moved upor down. After the adjustment and positioning, the fixing screw 5 isthen rotated to be tight by against the footing seat 4. The above statedadjustment of height of the elevated floor 2 is thus performed on theelevated floor 2 and is convenient for operation.

Referring to FIG. 4, by the fact that in practicing the presentinvention, the elevated floor 2 is directly pressed tight by using thefixing screw 5, hence the nuts used conventionally under an elevatedfloor can be saved, and the gross height of the elevated floor 2 can bereduced to be smaller than 4 cm after deducting the adjustment space ofthe tool, this breaks through the conventional limitation for anelevated floor. When the height after assembling of the elevated floor 2is largely reduced, the elevated floor 2 further leaves a sideward spacefor pipelines 60 without influence the goal of providing the elevatedfloor 2.

Referring to FIG. 5 showing application of the present invention to aconventionally designed elevated floor 2 (with a height larger than 4cm), by using the fixing screw 5, the present invention can also achievethe same function of locking and adjustment, and can be operatedcompletely on the elevated floor 2 and is more convenient in assembling.

The present invention thereby has the following advantages:

-   1. The present invention uses the fixing screw to press tight the    footing seat to reduce the gross height of the elevated floor to be    smaller than 4 cm, it is suitable for use in new and old buildings,    particularly in an old building wherein the planned spaces in floors    are insufficient, this can reduce waste of space and can avoid the    feeling of oppression.-   2. In using the present invention, with the fixing screw having a    through hole extending from top to bottom and being larger than the    adjustment hole of the footing seat, an adjustment tool can be    extended through the through hole from above the floor to be inlaid    in the adjustment hole for the convenience of adjusting height of    the elevated floor, which adjusting is performed on the elevated    floor rather than from a side of the floor, it is more convenient in    operation.
